Yeah Alex...the Skywatcher F/5 coma corrector works well when good spacing is achieved..... no doubt.
Oh,I forgot to mention in the review that this corrector(to my surprise) does reduce by .9 so, down to F/4.5 which might be wanted for some but, when you don't have much in focus and lots of light pollution maybe not wanted like my case.
Still, the main point is that SW F/5 coma corrector works well and If your paying a few hundred bucks or so that's the result you want
Oh by the way guys, If someone wants a raw fits file so they can have a closer clean look at the field just PM me and I'll email one out to you.
